Niveus EdgeAid Clear Aligner Polishing File - Dental Aligner Polisher, Emery Board for Clear Aligners, Aligner Tool for Rough Edges, Prevent & Relieve Orthodontic Discomfort & Mouth Pain

I never write reviews BUT THIS PRODUCT SAVED ME! This file saved me from sores and cuts all over my mouth and tongue from Invisalign! It works like a charm on my aligners I couldn’t be more grateful!

It's barely 3 inches long and that makes it difficult to use. It serves it's purpose, but if it were a little longer I would buy it again. But not at this small size.

Must have for anyone doing Invisalign.

Didn’t work as I thought it would

I've used this product for both plastic aligners and for nails - it's effective in both scenarios. For aligners, it works to get into small spaces, but I do find the polishing a bit rough (especially if you rub your tongue along your teeth/gums/aligner). I wish it would be a bit smoother.As for nails - this does a great job of filing rough edges and polishing up those spots, too. It's definitely not a tool I would use in place of a regular nail file for manicures. This file is good for those one-off broken nails that need a quick fix.Overall, I'd recommend this polishing file for either application.

It’ll work on one or 2. I had to change retainers every 2 weeks and the file was dull on the 3rd one. Cost still makes it a no brainer

Had a broken chipped tooth that had a razor sharp edge to it. Couldn't get a dental appointment right away, so I got this and it worked perfect to just take the sharp point down a fraction so it wasn't cutting up my mouth. Worked perfect, took about 15 seconds

File dulls after a few uses.
